The 2024 Ironman 70.3 World Championships in Taupō, New Zealand, delivered incredible – and very different – performances across both the men’s and women’s professional fields. While success on the global stage demands excellence across swimming, biking, and running, the bike leg is increasingly decisive for podium hopefuls. This year’s race proved the rule, as the top bike splits showcased riders on machines with incredible power, precision, and cutting-edge technology.
For the women, American Taylor Knibb secured her third consecutive world title with a bike split over four minutes faster than anyone else in the field. On the men’s side, local favorite Hayden Wilde (NZL) dazzled with the fastest bike split of the day but narrowly missed the top spot on the podium as he faded slightly in the final miles of the run. Across the board, the fastest bike splits demonstrated not only athletic prowess but also the technical aptitude to select the right gear to maximize performance given the terrain and conditions. The trend of 1x drivetrains continues to dominate the men’s field with an increasing number of top female cyclists also choosing to “go 1x.”
Let’s take a closer look at the bikes and gear that propelled the fastest cyclists at the 2024 Ironman 70.3 World Championships.
